Letters Patent No. 99.364. dated February I, 1870.

IMPRovED cLoTHEs-WRINGER.

-The Schedule referred to in these Letters Patent and making part of thesame.

Nature and. Objects of thelnvcntton.

The irst part of' my invention relates to a curved clamp, which, incombination with a thumb-screw at each end, is capable of securing thewringer to a tub; the object of this part of my invention being to pro-'vide an elast-ic clamp, adapted to attach the wringer irmly to tubs ofvarious sizes and thicknesses.

The second part of my invention relates to a journal-cap or bearing,arranged to regulate the movement of the springs and rollers, andconline them within speciiied limits.

The third part of my invention relates to a double inclined water-shed,beneath the rollers,l arranged to discharge the expressed `water fromeither side of the machine atpleasure.

Figure 2is a horizontal section through the'machine, at the centre ofthe curved clamp.

Figure 3 is a perspective view of the journal-cap, showing also theposition of the spring.

Figure 4 is avertieal section of the rollers and watershed, showingtheir relative position.

General Description.

A and B are the rubber rollers, between which the articles to be wrnngare passed, when the rollers are rotated by the crank and gears.

The rollerB has avfixed bearing in the upright pieces cf the flame C G,while the upper one is free to rise and fall within certain limits, itsbearings being the journal-caps D D.

Pressure is applied to the springs E F by means of the thumb-screw' G,(which passes through F, and the screw-plate H, attached thereto,) andhas the effect to separate the springs more widely when power isapplied.

A rubber spring is inserted at I, between F and the upper cross-piece J.

K is the water-board, for conveying the expressed water into a tub oneither side.

L is the curved clamp, for attaching the machine to a tub, and isoperated by the screws m m. v

N N ax'e thin plates ot metal, attached to the clamp L, to aid inwithdrawing it.

O is a thin strip, at the apex of the water-shed K, to direct the waterinto the proper tub.

I is the upright part of the bench, to which the wringer is attached;

joining each other.

' (1) the platform ofthe same;

ltIt, the hinges; and

S S, the cross-pieces.

In adjusting my wringer to a tub, I use the clamp L, which is curved onits inner face to about theshape ot' the side of a medium-sized tub,forming thus anarc ot'a circle, of about twenty-three inches diameter'.I'

give to vthis clamp suiicient elasticity to adapt it to tubs of varioussizes, by making it thin near its central part, and apply pressure nearits ends by the screws m mcausing it clasp the tub irmly. The points ot'`t-hese screws are provided with heads, which work behind pins or.plates of metal, N, attached -to the clamp, so that a reverse mot-ion ofthe screw relieves the pressure on the tub, and withdraws the clamp.

By introducing the head of this screw to its position through a recessin the end of the clamp, the plates N N could be dispensed with.

I am aware that a patent has been granted to a Mr. Glass, for acnrvedclamp, in combination with various other devices but my aim is toprovide a simple elastic clamp, receiving a positive motion, bothforward and backward, from the screws m m.

In the operation of wringing, the pressure of the springs E Fiscommunicated to the rollers through the bearing-blocks D D, the spring Etaking the position shown in dotted lines in Iig. 3.

The outer face of this block is extended upward, ,ab most to theupperspring, to 'regulate the motion-'of the lower spring, preventing itfrom lateral displacement, and also from rising beyond a specifiedpoint. This portion of the journal-block is marked D'. This limitationserves also to prevent so great separation of the rolls as to disconnectthe cogs.` I use this bear. ing at one or both ends, at pleasure.

Itis customary, in some wrin gers, to attach, beneath the rollers, asloping board or spout, tocarry again to the tub the water expressedfrom an article being wrung. These boards discharge only one way, alwaysinto the saine tub, until the machine is removed to another. I

remedy this defect, and enable the operator to wring from either of twoadjacent tubs, discharging the waste water into either tub at pleasure,by making this watershed slope hotliways from the under surface of thelower roller. This is of very great importance in such machines as areused on stationary tubs, set side y side, or in those used o n myimproved wringer-benc where the tups always occupy a cert-alli positionad- 'lhis water-shed, being flxed and permanent, requires no adjusting,the water being always expelled on that side from which the wet clothesare received, whether front or rear.

I nd it an advantage to insert, at the apex of this dmuble inclinedboard, a strip of leather, sheetrnbber, packing, or other material,projecting just enough to consisting of the journal-block D, providedwith its upward-projeetin g member D', the seme bein g arranged withrelation to the springs E and F, iu the manner and for-the purposes setforth.

3. In combination with the double-inclined wate'rshed K, theintermediate strip-O, constructed as und for the purposes described.
